What policy do I need to change to allow a Windows 2003 user name to include the '@' character ?

Thanks.

Under password policies in domain GPO, click on checkbox to select require complex passwords (I think 5 or 6th setting)

In a domain environment you should be able to no problem, without a GP setting.  Note that the Pre-Windows 2000 username replaces those special characters with underscores ( _ ).  So if your username was T@lly, the pre-2000 username would be T_lly.

If you are in a workgroup enviroment with 2003 server, I'll have to dig a bit deeper to find that out.

Surely you can't use @ in a domain username at all as it signifies the domain, i.e  user@yourdomain.internal.

This isn't a domain user - it's a local user on a Windows 2003 server.

But if it did work how would it know that steve@otherhalfmyname is the whole username or it should look for steve on the otherhalfmyname domain?

If you put an @ it's going to look for a domain, and won't find it.
